Test kernels for mipsel: bcm947xx and r5k-cobalt

Hi all,

I have build some tests kernels for mipsel.

The first one [1] concerns bcm947xx CPU, which is found for example in the WGT634U routers. It is based on tbm's kernel [2], but using a 2.6.16-7 kernel. I have enabled a few USB and network modules, and module autoloading. I have started to remove some of the Broadcom OS layer, the patches are now 40kB smaller. I have continued to clean the patches, but I haven't tried to build a kernel with them yet.

The second kernel [3] concerns r5k-cobalt CPU. I have enabled a few network modules (after all this box is designed to be a server) using the amd64 configuration file as an example. I also enabled CONFIG_IDEDMA_PCI_AUTO which improves the hard-disk speed as shown below:

Debian kernel, after boot:
 Timing buffered disk reads:   10 MB in  3.11 seconds =   3.21 MB/sec
Debian kernel, after enabling DMA with hdparm:
 Timing buffered disk reads:   30 MB in  3.15 seconds =   9.52 MB/sec
New kernel:
 Timing buffered disk reads:   36 MB in  3.11 seconds =  11.56 MB/sec

I am using it for a few days without problems. It would be nice if some people could test it, and if it works well, I think this configuration file could be used in official Debian kernels.

Sorry if the test kernels are a bit outdated compared to the Debian kernels, but the kernel team upload kernels faster than what my CPU can build :)
